Characterizing tumor microenvironment biomarkers

Investigating impact on cancer progression

The discovery and development of effective cancer immunotherapy requires a better understanding of the tumor and its surrounding environment. Different stages of cancer progression depend on the tumor, the organ in which it resides, and the immune response. The innate and adaptive immune response and the associated cellular molecular factors influence tumorigenesis and the biochemical makeup of the tumor microenvironment. Profiling genotypic to phenotypic markers is useful for predicting drug response or elucidating the mechanisms of resistance to therapy. To help researchers investigate the relationship between the cellular and extra-cellular features of a tumor and the immune response Thermo Fisher Scientific offers a broad portfolio of solutions.

Characterizing cytokine profiles within the tumor microenvironment

Cytokines are low–molecular weight proteins that mediate communication between cells in the tumor microenvironment. Immune cells (e.g., macrophages and lymphocytes) and stromal cells (e.g., fibroblasts and endothelial cells) release cytokines to affect cell differentiation, growth, survival, migration, and immune cell activation. Cytokines may have a wide impact on cancer cells ranging from being anti-tumorigenic to influencing various stages of tumorigenesis. Early responses of inflammation as well as later changes such as cellular transformation and malignancy are a result of balancing pro- and anti-inflammatory cytokines, cytokine receptor expression patterns, and the cellular make-up of the tumor microenvironment. Table 1 below highlights key features of cytokines, chemokines, and growth factors commonly associated with propagation of tumor-associated inflammation.

Molecular profiling of co-inhibitory and co-stimulatory transcripts in tumors

In addition to co-inhibitory and co-stimulatory checkpoint molecules and cytokine and chemokines that can identify cell-type specific markers, RNA analysis can help to understand their related upstream transcriptional processes and pathways. The ability to perform high-content gene expression profiling allows for the simultaneous analysis of multiple pathways in addition to monitoring immune activation. The QuantiGene Plex assay enables direct quantification of mRNA and lncRNA targets directly from any sample including fresh, frozen or FFPE tissue and whole blood.
